Currently, no messages are printed when mounting a CIFS filesystem and no debug configuration is enabled. However, a CIFS mount information is valuable when troubleshooting and/or forensic analyzing a system and finding out if was a CIFS endpoint mount attempted. Other filesystems such as XFS, EXT* does issue a printk() when mounting their filesystems. A terse log message is printed only if cifsFYI is not enabled. Otherwise, the default full debug message is printed. In order to not clutter and classify correctly the event messages, these are logged as KERN_INFO level. Sample mount operations: [root@corinthians ~]# mount -o user=administrator //172.25.250.18/c$ /mnt (non-existent system) [root@corinthians ~]# mount -o user=administrator //172.25.250.19/c$ /mnt (Valid system) Kernel message log for the mount operations: [ 450.464543] CIFS: Attempting to mount //172.25.250.18/c$ [ 456.478186] CIFS VFS: Error connecting to socket. Aborting operation. [ 456.478381] CIFS VFS: cifs_mount failed w/return code = -113 [ 467.688866] CIFS: Attempting to mount //172.25.250.19/c$ Signed-off-by: Rodrigo Freire <rfreire@redhat.com> Signed-off-by: Steve French <stfrench@microsoft.com> |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
